What type of bond holds the growing RNA strand to the DNA template strand?
a. hydrogen bonds
b. hydrophobic interactions
c. covalent bonds
d. ionic bonds
Option a is Correct. The developing RNA strand is held to the DNA template strand by a form of bond known as a hydrogen bond.
The nucleotides that make up DNA and RNA are joined together in a chain by chemical interactions, known as ester bonds, between the sugar base of one nucleotide and the phosphate group of the neighboring nucleotide.
With the help of intramolecular hydrogen bonding between complementary bases, single-stranded RNA may also generate a variety of secondary structures in which a single molecule folds over and forms hairpin loops.
The bases, sugars, and phosphate groups are tightly bound together by covalent bonds that occur within each linear thread (both within each component and between components). Between the two strands, hydrogen bonds are formed by the complementary pairing of a base from one strand with a base from the other.

Why is the oxidation of NADPH energetically favorable?O None of these answers O The reduced form of NADPH is more stable than the oxidized form. O The biosynthetic reactions that are coupled to NADPH oxidation are energetically favorable. O NADPH is the form of the molecule that can gain two high-energy electrons. O The oxidized form, NADP+, is more stable than the reduced form NADPH O Oxidation of NADPH breaks a high-energy phosphoanhydride bond. .
Option 6 is Correct. Oxidation is advantageous energetically. This is due to the high-energy phosphoanhydride link being broken by NADPH oxidation.
As a result, these processes are more energy-beneficial than the biosynthetic events connected to NADPH reduction. NADPH is more stable in its oxidised state than in its reduced state. NADPH is made up of two very energetic electrons. As NADP+ is more stable in its oxidised state than in its reduced state, losing these electrons in an oxidation process is energetically advantageous (NADPH).
Nicotinamide Adenine Dinucleotide Phosphate (NADP) can be found in two states: oxidised (NADP+) and reduced (NADPH). First of all, NADPH is an electron and hydrogen acceptor. These particles are simultaneously transferred to the NADP+ molecule by the specific enzymes. When it accepts the electrons in this process, NADP+ decreases.

why are there so many types of organisms and why are their distributions so restricted?
There are a huge variety of different creatures, and due of geological age and manmade disturbance, respectively, their distribution is rather constrained.
Endemism is the term used to describe a species' limited range or presence in a single geographic location.
Geological age has been one of the key theories; older groupings of organisms are more diverse simply because they have had more time to amass more species.
Anthropogenic disturbance, which affects species ranges through habitat loss, alteration, or degradation, pollution, disease, the introduction of non-native species, over-harvesting, and global climate change, is one of the most prevalent causes now limiting the distribution of species.
The survival and reproduction of a species, and consequently its local density and regional range, may be hampered by both physical (temperature, rainfall), as well as biotic (predators, competitors), variables.
Food, water, habitat, and mates are the typical ecological limiting variables. The carrying capacity of an environment will depend on the accessibility of these elements. Demand for food increases along with population growth. Food is a scarce resource, so organisms will start to fight for it.

River erosion gizmo answer key
River erosion is the process of a river wearing away rocks and soil as it flows. This can happen through a variety of mechanisms, including abrasion (the grinding away of rocks by sediment carried by the river), hydraulic action (the force of the water itself eroding the riverbed), and chemical weathering (the breakdown of rocks through chemical reactions with the water).
How does river erosion occur?Here are the main ways in which river erosion occurs:
Hydraulic action: This is the force of the water itself as it flows and hits against the riverbanks and bed. The force of the water can loosen and remove rocks and soil, particularly in areas of high turbulence or where the flow is particularly fast.
Abrasion: This is the process of rocks and other materials in the water being carried along by the flow and rubbing against the riverbanks and bed, slowly wearing them away. The effect can be particularly strong during times of high flow or flooding, when larger materials are carried along.
Attrition: This is the process by which rocks and other materials carried by the river collide with each other, gradually wearing themselves down into smaller particles. These smaller particles are then carried along by the river, contributing to further erosion.
Solution: This is the process by which certain types of rock and soil are dissolved by the acidic water in the river, contributing to further erosion. This process is particularly important in areas with limestone or other soluble rocks.
